Large language models have been shown to achieve remarkable performance across a variety of natural tasks using few-shot learning, which drastically reduces the number task-specific training examples needed adapt model particular application. To further our understanding impact scale on we trained 540-billion parameter, densely activated, Transformer model, call Pathways Language Model PaLM. We PaLM 6144 TPU v4 chips Pathways, new ML system enables highly efficient multiple Pods. demonstrate...
Recent neural network-based language models have benefited greatly from scaling up the size of training datasets and number parameters in themselves. Scaling can be complicated due to various factors including need distribute computation on supercomputer clusters (e.g., TPUs), prevent bottlenecks when infeeding data, ensure reproducible results. In this work, we present two software libraries that ease these issues: $\texttt{t5x}$ simplifies process building large at scale while maintaining...
We discuss the physics case for and concept of a medium-scale axion helioscope with sensitivities in axion-photon coupling few times better than CERN Axion Solar Telescope (CAST). Search an axion-like particle these couplings is motivated by several persistent astrophysical anomalies. present early conceptual design, existing infrastructure, projected sensitivity timeline such (Troitsk Experiment, TASTE) to be constructed Institute Nuclear Research, Troitsk, Russia. The proposed instrument...
This paper describes new three-dimensional algorithms of stochastic data transformation, offering a solution for information security problems. The most important feature these is high degree parallelism at the level elementary operations. In this we present 3D transformation called DOZEN, inspired by AES cipher, and two constructions S-box, 2D S-boxes respectively.
In this paper, the effect of organo-modified montmorillonite (oMMT) on properties and structure ultrahigh molecular weight polyethylene (UHMWPE) are studied. A technology for preliminary mechanical activation oMMT in a planetary mill was proposed. Using methods scanning electron microscopy IR spectroscopy, morphology were studied before after mill. It has been found that leads to dispersion an increase porosity oMMT. Heat treatment at temperature composite material processing does not result...

In the paper, author applies constitutional law positions in order to study key aspects of a number stages comprehensive reform state control (supervision), municipal and public their systemic unity Russian Federation. The makes following conclusions proposals: 1) next stage supervisory activities has now begun its main direction may become reduction unnecessary inspections expansion preventive measures, which can be reflected Concept being prepared 2022–2024; 2) development further...
In this note we present a mathematical framework for rigorous approach to common track fit trackers located in the inner region of ZEUS detector. The makes use Kalman filter and offers treatment magnetic field inhomogeneity, multiple scattering energy loss. We describe details implementation technique with reduced amount computations cylindrical drift chamber, barrel forward silicon strip detectors straw chamber. Options homogeneous inhomogeneous are discussed. fitting tracks one event takes...
Based on the systematic approach, author shows key elements of consistency legislation state control (supervision), municipal and public formulates main integrative properties relevant set legislative acts that allow it to be considered as an integral system in context constitutional law at present time. It is noted future, when improving control, one hand, other special attention should paid further convergence their basic norms, primarily norms-principles norms-goals form value-semantic...
